openwrt on napp-it all-in-one / read only

[solaris12]

Hi all
I just finished to build my napp-it all-in-one, I am pretty happy with it. except that I fould my openwrt always show / read only.

my datastore is on 4 sasdisk on zfs raid-10 mounted via NFS from napp-it. after I put openwrt vm on datastore1 which is another 2.5 sata disk where napp-it on, it works like a charm.

I am wondering how to fix it?

thanks

after change scsi controller to vmware paravirtual , it is stable now. it has nothing to do with zfs/nfs
